SPECIFICATION forming part of Letters Patent No. 658,503, dated September 25, 1900.

Application filed February 23, 1900. Serial No. 6,234. (No model.)

To all whom it may concern: same end with cable 2 and intermediate be- Be it known that 1, GEORGE H. MCBRIDE, tween the center and the opposite outer side,

a citizen of the United States, residing in the extends diagonally across to the other end toa city and county of San Francisco, State of point intermediate between its center and the 5 California, haveinvented an Improvementin end opposite to the one near which cable 4 Bed-Bottoms; and I hereby declare the folstarts. Cables 3 and 5 start at points interlowing to be a full, clear, and exact descripmediate between cables 2 and 4, and the cention of the same. ter of the end bar a, from which I have de- My invention relates to improvements in scribed all these cables as starting, and ter- IO elastic bed-bottoms. minate at the same points between the ends It consists in the novel combination, with of cables 2 and 4 on the opposite end bar Z) of a frame and a mattress which is carried therethe frame, cable 6 starting near the ends of on,oflongitudinally-disposed spirally-woventhe end bar a and terminating near the ends wire cables so intertwined and extended diagof the end bar b. I5 onally across the frame as to provide an elas- In constructing this bed-bottom the cables tic support for the mattress and reinforces at 2 and 5 and 3 and 4 are twisted together with points where the greatest weight and consetwo or more turns at a point intermediate bequent depression of the mattress is liable to tween the end a and the center of the, frame, fall. this point being located approximately where 2o Myinvention also comprises details of conit will lie beneath the shoulders of an occustruction which will be more fully explained pant of the bed. From this point the cables by reference to the accompanying drawings, 2 and 4 are carried to the center, where they in whichare twisted together by several turns, thus Figure l is a plan of my invention. Fig. 2 combining them for a considerable length at 25 is a transverse section on the line 0c 00. about the center of the longitudinal length The object of my invention is to provide a of the bed. From this point these cables 2 support for wire and like mattresses by the and 4 diverge, and again meeting the cables employment of spirally-wound tubular cables 3 and 5 they are again twisted with these ca- I having longitudinal elasticity and the combles at a'point approximately as near the end o bination of such cables in a manner to prob as the first twists were near the opposite vide for greater bearing strength at points end, thus forming another reinforce and supwhere the greatest depression of the mattress port at this end, so that if desired the bed is likelyto occur, such as the center and points can be made up with the shoulders at either where the shoulders of the occupant of'the end, and the reinforcing-support will be 5 bed will lie. In this combination Itwist any found for the shoulders at whichever end of two or more of the cables together at interthe bed the head may be placed. The cables vals, so as to form enlarged and immovable 3 and 5 after leaving the point where they sections in which the intertwined cables reinare intertwined with 2 and 4 are carried outforco each other and correspondingly increase wardly toward the side frames A and are 0 40 the supporting strength at their intertwined there intertwined by a number of turns with points. the cables-6, which at this point approach As here illustrated, A is a frame of any nearer to the longitudinal center of the bed, suitable size or description, such as is emand after leaving this point of intertwining ployed for a base for mattresses. the cables 6 again diverge to near the ends 5 5 The hollow longitudinally-elastic cables are of the end bar b. These intertwined portions l united as follows: Commencing ata point inof the cable are so twisted and secured totermediate between the middle and one of the gether that there is no possibility of any slipend bars of the frame, a cable 2 extends diagoping or sliding of the cables over each other, pally across to a point intermediate between as this would nullify any reinforcing strength ioo' 5c the middle and opposite end of the opposite which I design to provide by thusuniting the l end barof the frame A. Cable 4,starting atthe cables at intervals. I have thus by this inbed. It will be manifest that the number of these reinforces may be increased by increasing the number of cables which are employed.

The central cables having been intertwined, the side cables 6 are then drawn as tightly as possible in the direction of their length by any suitable screw, turnbuckle, or other equivalent device. verse separation of the intertwined portions This provides a trans of the intermediate cables, and they can be thus drawn to any required tension.

Having thus described my invention, wha I claim as new, and desire to secure by Letters Patent, is

1. In a bed-bottom and in combination with the frame thereof, a series of longitudinallyelastic cables extending diagonally from one end bar to the other end bar of the frame, intermediate cables fixed at each end between the first-named cables and the center and intertwined therewith near each end and with each other at the centerand immovable with relation to each other.

2. In a bed-bottom, longitudinally-elastic cables having their ends secured to the end frames of the bed-bottom, similar cables attached to one end of the bed-bottomexterior to the first-named cables, extending diagonally across to points on the other end eqn ally distant from the opposite sideof the frame,

said first-named cables being rigidly inter v twined with the diagonal cables at points near the ends of the frame, and'the diagonally-disposed cables being intertwined with each other at their point of crossingand midway between the ends of the frame and means for diverging the central cables outwardly toward the sides of the frame intermediate between the ends.

3. In a bed-bottom, longitudinally-elastic cables attached toeach end of the frame upon each side of the center, othercables attached to one end frame outside of the first-named cables, rigidly and immovably intertwined therewith at a point between :the said end and the center of the bed, thence meeting and immovably intertwined with each other centrally of the length of the bed, thence diverging toward the opposite side from the starting-point and again intertwined with the first-named cables and having their ends finally fixed to the opposite end of the frame at points diagonally opposite from the attachment to the first-named end, other cables connected to each end frame near the side frames and immovably intertwined with the outwardly-diverging central cables near the center of the length of the frame.

4. In a bed-bottom, a rectangular frame, longitudinally elastic cables having their ends fixed to one end of the frame upon each side of the center, diagonally-extending cables fixed to the same frame exterior to the firstnamed cables and immovably intertwined therewith between their points of attachment and the center of the bed, said diagonal cablesconverging and being immov ably intertwined with each other at the lon gitndinal center, and the first-named cables diverging from their point of union with the diagonal cables, other cables having their ends attached near the corners of the frame, and the central portions immovably intertwined with the diverging central cables whereby three reinforced lines are formed at the middle of the bed, and said central cables thence convergingand again immovably intertwined with the diagonal cables which diverge from each other and toward opposite sides of the :end frame from their first point of attachment.

5. In a bed-bottom,the combination of pairs of longitudinally-elastic cables fixed to the ends of the mainframe with the membersof the same pairs immovably intertwined near the ends, one member of one pair of cables intertwined with a corresponding member of another pairat a point near the center of the bed, and means for diverging the remaining member of each of said pairs toward the sides of the frame.

In witness whereof I have hereunto setmy hand.
